Jesus reveals His Divine origin and His Divine power He manifests through His various miracles, but His union with the Father, and the full breadth of God’s love, Jesus shows on the cross.
The Cross is the Love of God — Father, Son, and Holy Spirit — outpoured. It is a Trinitarian Act, for it is the Divine Will, the submission of the Son, and the pure Gift of the Holy Spirit between the Father and the Son that opens the floodgates of Heaven’s mercy upon creation, once wounded by sin but now saved by grace.
St. Paul writes the following in his letter to the Philippians 2:6-11:
Though he [Jesus] was in the form of God,
he did not regard equality with God
as something to be grasped.
7
Rather, he emptied himself,[b] taking the form of a slave,
being born in human likeness.
Being found in appearance as a man,
8
he humbled himself,
and became obedient to death,
even death on a cross.
9
Because of this, God greatly exalted him
and bestowed on him the name
that is above all other names,
10
so that at the name of Jesus
every knee should bend
of those in heaven and on earth and under the earth,
11
and every tongue should proclaim
to the glory of God the Father:
The Son’s mission from the beginning was to reveal the Father’s Love through His willful obedience, so that He could win for us the crown of salvation, and send the Holy Spirit as our Advocate.
Jesus reveals His divine origin through His suffering and death, and it is by this suffering and death that we merit grace to receive once again the life of God, once lost through the sin of the first Adam, now restored through the God-man, Jesus.
